wit-1 pinion 18 will be shi .mounted thereon and having an in a collar or yolre- LllG end oi a shifting lever E that may be employed to slide the sleeve 1S -2O and attached pinion 18 on the shaft in order to cause said pinion to mesh with either one the ear-xvi eels or to be brought to a position between them. The shifting mechanism referred to is not shown, as the construction. of such devices well under stood.

24 indicates a stop at the outer end of the. squared portion 4 of the shaft against which the end of the sleeve will abut when orawn back to bring the pinion l into full engagement with the internal gear 17. This stop, shown in 2, is in the form of a ring which' is held in place by a pin 25 passing through it and toe sha t.

With the device in use it will be understood that the teeth 7 and 12 of the gearwheels 5 and 11, respectively, will be in engagement with a smaller and larger gear, respectively, on a shaft to be driven, and, accordingly as it is desired to drive such lastanentioned shaft faster or slower, the d on the extended hub 6, in the manner already described, to bring it into engagement with either the internal gear 9 or internal gear 17. When it is desired to drive neither of the gearwheels 5 or 1 1 the pinion will be shifted to bring it between said two gears, as shown in Fig. 1. V lhen either of the gear-wheels 5 or 11 is being positively driven through the pinion 18, there is no driving power being exerted by re other, and owing to the smooth surfaces of the outer face of the flange 10 and the insurface of the projecting or flange-like rim of the geanwheel 11 that are in contact with each other, the relative movement of these two parts'will cause but little friction and consequently but little loss of power.

As will be understood from the deseri tion of the construction of the mechanism, the several parts can be readily and easily as seinbled or separated, and when assembled as shown constitute a cheap, simple, cornpact and durable device by which a driven shaft can be instantly set in motion at either one of two speeds.

What I claim as my invention and desire to secure by Letters Patent is 1. In a device of the class described, the combination with a shaft and a wheel loosely mounted on said shaft and rovided with an internal gear and a laterally-extending annular flange, of a second wheel. loosely supported on said flange and also rovided with an internal gear, and clutch evice secured to and slidingly mounted upon said shat adapted to be moved into engagement with either of said internal gears. 2. In a device of the describe! 1 combination with shaft and a wheel loo r I gear and a la tcrally-cictending annular Elaugc,

scenes of second wheel also provided with an inernal' gear and loosely supported on said lange, means for retainin said second Wheel on said flange, and a clutcli device secured to 3. in a device of the class described, the coiiobination with a shaft and a wheel loosely mounted thereon and having an internal gear and a laterally-extending annular flange, of a second wheel also provided with an internal mg secured to the face of the fir t-mentioned wheel and engaging a projecting edge of the im of said second-menti0ned wheel, and a clutch device. secured to and slidingly mounted upon said shaft and adapted to be moved into engagement with either of said internal gears.

e. in a device of the class described, the combination with a shaft and a wheel loosely mounted thereon and having an internal gear and a laterally-extending annular flange, of a second wheel also provided with an internal and loosely supported on said flange, the webs or body portions of said wheels being separated. so as to leave a space between them, and a clutch device secured to and slidingly mounted upon said shaft and adapted to be moved into engagement with either of said internal gears or to be moved into the said space between thesaid two gear-wheels.

5. in a device of the class described, the combination with a shaft and a. Wheel having an extended hub portion that is loosely mounted on said shaft, said wheel being provided with an internal gear and also with an annular flange that extends from one face of the wheel, of a second wheel also provided with an internal gear and loosely sup orted on. said flange and having a large contra open ing, a clutch slidingly mounted on said hub portion, and a sleeve attached to said clutch, said sleeve extending through the said 0 ening in said second-mentioned wheel and aving a sliding but non-rotatable engagement with said shaft.

6. In a device of the class described, the combination with a shaft and a wheel loosely mounted on said shaft, said wheel being provided with a laterally-extending annular flange and having a recess in one face, of a second wheel loosely su ported on said flange, said second wheel being provided with a central opening, and -a clutch device secured upon said shaft and ads 'ted to be moved into either the recess in sai first-mentioned wheel or the central opening of the second-mentioned wheel.
